From:  Wang Zeep <G.ZEEP%MIT-EECS@MIT-MC.ARPA>

There is no second law of thermodynamics.  There is, however, a postulate 
that something like entropy exists (with a long list of properties) and 
another postulate that it tends to reach a maximum with respect to
unconstrained variables.  This 1st, 2nd, 3rd "law" stuff is strictly
19th century (well, part of the 20th).

Read Laszlo Tisza, "Generalized Thermodynamics" or Herbert Callen, "Thermody-
namics".

Summary:  They aren't laws, just postulates. (and they have been verified
to break down with very large or very small systems.)
